small size and thin substance. The dried specimens appear like a. 

 thin skin. Phallus tenuis was originally from Java, but must be a 

 rare species there, as Dr. Bernard does not record it. It occurs also 

 in Ceylon (specimens at Kew), and Professor Kusano has found it 

 (very rarely) in Japan. In the latter country it grew on rotten wood. 

 The stipe of the Javanese form is yellow, but in Japan it was repre- 

 sented as white. The original description makes no mention of the 

 plant having a veil, but one of Penzig's figures shows a rudimentary 

 veil hidden under the pileus. 



PHALLUS FAVOSUS (Fig. 4). This species, also known from 

 Java, and rare there, is intermediate between Phallus impudicus and 

 Phallus tenuis. With the large size of the former, it has a relatively 

 thin pileus and a pale, yellowish stem. The substance of the pileus 

 is also pale, but not so clear yellow as that of tenuis. It is only 

 known from the original record. 



PILEUS RELATIVELY SMOOTH OR MERELY RUGULOSE. 



PHALLUS RUBICUNDUS (Fig. 5). Stem, red. Pileus, red,, 

 smooth, or slightly rugose, covered with the greenish gleba. Apex, 

 perforate, or sometimes imperforate. This is the only red species of 

 the genus Phallus that we have, and it is widely distributed. It oc- 

 curs in abundance in certain localities in our Southern States and 

 many other warm countries. It has been named from India (Phallus 

 aurantiacus), Africa (Phallus sanguineus), Australia, Hawaii. I have 

 seen a drawing from China, and it is reported from Japan. In Hawaii 

 it has been shown to be the cause of a destructive root disease of the 

 sugar cane. When we get a better knowledge of the distribution of 

 our phalloids, I think that Phallus rubicundus will be found in almost 

 all sugar countries. I believe there is only one red Phallus. Forms 

 from various countries seem to differ in being slender or obese ; 

 the pilei, in being truncate or acute, perforate or imperforate, with 

 an apical collar or without, but the material is not at hand from 

 which to form any opinion as to the systematic value (if any) of these 

 differences. 



Forms. 



PHALLUS GRACILIS (Fig. 6). Phallus rnbicundus varies chiefly in 

 stature. Slender forms have been called Phallus gracilis. For a long time 

 the characters of Phallus rubicundus were not known other than the fact that 

 we had a, red Phallus in our Southern States. A recent article of Professor 

 Long has given us a clear idea of its characters and convinced us there is no 

 distinction Between it and Phallus aurantiacus as it has generally been known 

 in foreign countries. 



PHALLUS RAVENELII (Fig. 7). This is the most common 

 phalloid of the United States, there replacing Phallus impudicus of 

 Europe. In general appearance it resembles Phallus impudicus, but 

 has a smoother pileus and a veil, usually short and hidden under the 

 pileus. Rarely, however, it occurs with a protruding veil (Fig. 8). 

 Usually Phallus Ravenelii grows on logs in the woods, sometimes on
